If you don't handle those things like most people do, then you have to toughen up, grow some backbone. Life's tough, job interviews are tough, most jobs involve situations that'll put you under pressure, and then you have bills, car insurance, things breaking down at the house, etc.
At a job interview, you need to give employers what they want to hear. They don't want you to tell them anything that can imply that you're unreliable. All they care about is that the person they hire is capable of filling that position and getting the job done. This is why you should do some research on a company before you go in for an interview. If you know what they do, you can manipulate your speech in a way that makes them know/believe that your skills are what they need, otherwise they'll just pick someone else, someone who's more confident, more capable, more ready to handle whatever the job brings.
